fermentation of sugar

13- A reaction of great social significance is the fermentation of sugar with yeast. This is a zero-order (in sugar) reaction, where the yeast is a catalyst (it does not enter the reaction itself). If a 0.5-L bottle contains 4 g of sugar, and it takes 30 min to convert 50% of the sugar, what is the rate constant?

14- A radioactive waste from a clinical laboratory contains 0.2 µCi (microcuries) of calcium-45 (45Ca) per liter. The half-life of 45Ca is 152 days. How long must this waste be stored before the level of radioactivity falls below the required maximum of 0.01 µCi/L?
